Abstract (en)
A physical quantity measuring device (1) includes: a first light source (11) configured to output a first light (L1); a second light source (12) configured to output a second light (L2); an optical sensor (40) letting in the first light (L1) outputted from the first light source (11) and outputting a measurement light (M1) according to a physical quantity of an object and the first light (L1); a wedge (62) configured to let in the measurement light (M1) and the first light (L1) outputted from the optical sensor (40) and output a first outgoing light and let in the second light (L2) outputted from the second light source (12) and output a second outgoing light; a first light path for the first light (L1) outputted from the first light source (11) to be outputted to the optical sensor (40) and for the measurement light (M1) and the first light (L1) outputted from the optical sensor (40) to be outputted to the wedge (62); and a second light path for the second light (L2) outputted from the second light source (12) to be outputted to the wedge (62).
